TfL Ref: 1875-2425

 

Thank you for your request received by Transport for London (TfL) on 9 September 2024 asking for information about the Hogarth roundabout.

 

Your request has been considered in accordance with the requirements of the Environmental Information Regulations and our information access policy.  I can confirm that we hold the information you require. 

 

 

By way of background, Hogarth Roundabout is a scheme on the Safer Junctions programme which was established in 2017 by TfL to tackle the 73 junctions in London with the worst safety record. TfL have made safety improvements at 45 of the 73 junctions to date and are committed to making improvements at the remaining junctions.

 

The list of the 73 junctions was developed using analysis of casualty figures on the TfL road network, focussing on the 73 junctions which saw the highest number of collisions involving pedestrians, cyclists and motorcyclists between 2012 and 2015.

 

We are aware that the safety record at junctions changes over time and therefore the position of any junction in a ranked list of locations is subject to change. It is the case that Hogarth roundabout still features in the top 10% of junctions in London with a poor safety record and is a location that we have prioritised to make safety improvements in the future.

 

When considering road safety risk, TfL consider the number and severity of collisions and casualties at each major road and junction (or 'node') in London. At each location, a severity-weighted harm score is calculated and compared with the network average. Roads and junctions are ranked according to the extent to which their harm score is higher than the network average, enabling the prioritisation of investment. A node is a junction or roundabout which consists of two or more classified roads – the area is generally 50M in radius but can be up to 200M radius as in the case of Hogarth roundabout.

 

This attached dataset is based on 3 years of collision data to December 2023. The harm score at Hogarth Roundabout (which is named Hogarth Lane/Burlington Lane in the data, Node ID: 25_168) is higher than the TLRN network average. The magnitude of this difference places this roundabout as the junction with the 239th highest harm score out of 4,821 junctions considered. Please note that the data in the attached table includes all nodes in London on both the borough network and the Transport for London Road Network.
